INCUBATOR.

SPECIFICATION forming part of Letters Patent No. 659.529, dated October 9, 1900. Application filed January 26, 1900. serial N0. 2,884. \NO model.)

To ctZZ whom, it may concern:

Be it known that I, JOHN H. HUGHES, a citi- Zen of the United States, and a resident of Miauus, in the county of Fairiield and State of Connecticut, have invented a new and Improved Incubator, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved incubator which is simpleaud durable in construction and arranged to insure properheating and ventilation without the use of dampers or other mechanical contrivances.

Theinvention consists of novel features and parts and combinations of the same, as will be fully described hereinafter,and then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure l is a perspective view of the improvement. Fig. 2 is an enlarged vertical section of the same on the line 2 2 in Fig. 3. Fig. 3 is a sectional plan view of the same on the line 3 3 in Fig. 2, and Fig. 4 is a similar view of the same on the line 4 4 in Fig. 2.

The incubator as a whole is arranged in a boX or casing A, mounted on suitable legs B, and in the casing A is formed an egg-chamber C, containinga suitable drawer ordrawers D, having perforated bottoms D, on which rest the' eggs to be hatched. Below the eggchamber, directly under the bottom D, is a foul-air chamber E, and above the said chamber C and a distance above the top of the drawer D is arranged a heating tank or chamber F, preferably having sets of connected compartments F F as is plainly shown in Fig. 4, a longitudinal partition F being between the chambers and extending from the front face of the casing to within a short distance of the rear end thereof. The compartments F are connected at the front of the casing with the ends of a heating-pipe G, from which leads a pipe G, having a hood G under which is located a lamp H or other suitable heating medium, so that the products of combustion pass up the pipe G into the pipe G and from the latter into the compartment F, to travel along the same, and finally pass at the rear end into the compartment F back to the front of the casing, to finally pass out of the compartments F by suitable discharge-pipes 1, extending upward a short distance, as indicated in Figs. 1 and 2. By the arrangement described the heat is circulated through the compartments F F so as to heat the egg-chamber uniformly and at the same time heat the fresh air passingthrough the air-chambers J, located over the chamber F, as indicated in Figs. 2 and 3.

The air-chambers J are provided at the front of the casing with air-inlet pipes K, and the rear ends of said chambers are connected by downwardly-extending ducts L with the upper end of the egg-chamber O at the rear end thereof, as will bereadily understood by reference to Figs. 2, '3, and 4.

The front end of the foul-air chamber E is connected by pipes N with airdischarge chambers 0, located over the chamber F, betweenthe chambers J, is plainly indicated in Fig. 3, and the rear ends of said chambers O are provided with air-discharge pipes P, leading to the outer air. It is evident that by the arrangement described the air entering and passing through the chambers'J is heated by the heat emanating from the heating-tank F, below the said chambers, and this fresh-heated air passes through the ducts L into the egg-chamber and through the drawer D therein, thus passing over the eggs, and thereby uniformly heat the same by coming in contact with the eggs. Air then passes down into the foul-air chamber E, and then passes from the latter through the pipes N into the discharge-chambers O, in which the foul air is heated, to insure proper circulation through said chambers, and to the pipesP, leading to the outer air.

From the foregoing it is evident that the heated fresh air after passing through the egg-chamber is carried from the foul-air chamber to the discharge-chambers 0, connected with the outer air by way of the pipes P, and consequently a uniform and natural circulation of air is obtained through the chambers J, the ducts L, the egg-chamber O, and the foul-air chamber E without the slightest danger of any foul air coming in contact with the eggs or any over or under heated air passing into the air-chamber 0. By the ar- Having thus fully described my invention,

I claim as new and desire to secure by Letters Patent- 1. An incubator, comprising an eg -cham-i her, a heating-tank arranged above said egg chamber and connected with a source of heatsupply, a foul-air chamber below the said eg -chamber, and air-inlet and air-discharge chambers located above said tank, the airinlet chamber beingconnected with the egg chamber at one end and having an air-inlet opening at its opposite end, and saidloutletchamber being connected with the foul-air chamber at the end opposite to the one at which the air enters the egg-chamber and having an air-outlet opening at its other end, substantially as shown and described.

2. An incubator, comprising an egg-chamber having a drawer with a perforated bottom, a heating-chamber arranged above said egg-chamber and connected with a source of heat-supply, a foul-air chamber below said drawer, and air-inlet and air-discharge chambers above said tank, the air-inlet chamber having an air-inlet opening at its front end and connected with the egg-chamber at the rear end, and said outlet-chamber being connected with the foul-air chamber at the front end and having an air-outlet at its rear end,

so that fresh air circulates through the eg chamber from the air-inlet chamber to the foul-air chamber, substantially as shown and described.

3. An incubator, comprising an egg-chamber, a heating-tank above said egg-chamber, a foul-air-chamber below said egg-chamber, spaced-apart air-inlet chambers having airinlet openings in their front ends and connected with the egg-chamber at their rear ends, and air-discharge chambers between the inlet-chambers,said discharge-chambers being connected with the foul-air chamber at -the=front and having air-outlet openings at the rear, as set forth.

4. An incubatoig com prising an egg-chamberhaving a drawer, a=heating-tank arranged abovesaid egg-chamberand connected with a source of heat-supply, a foul-air chamber below saiddrawenza set of air-inlet chambers above said tank having outlet-openings at one end, and connected by duets with said egg-chamber at the top thereof near the opposite end, and air-discharge'chambers connected with the foul-air chamberiat one end and having outlets to the open air at the other end, said air-discharge chambers being located over said tank, substantially as shown and described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JOHN H. HUGHES.
